B) [tex]\frac{2}{3}[/tex]

C) [tex]\frac{14}{11}[/tex]
D) [tex]\frac{3}{4}[/tex]
E) [tex]\frac{1}{2}[/tex]
F) [tex]\frac{1}{12}[/tex]
G) [tex]\frac{7}{3}[/tex]
H) [tex]\frac{5}{4}[/tex]
I) [tex]\frac{62}{15}[/tex]
J) [tex]\frac{3}{5}[/tex]

Explicação passo a passo:

A) [tex]\frac{1}{4} +\frac{5}{4}[/tex]

[tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

B) [tex]\frac{7}{9} -\frac{1}{9}[/tex]

[tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex]

C) [tex]\frac{18}{11} - \frac{4}{11}[/tex]

[tex]\frac{14}{11}[/tex]

D) [tex]\frac{1}{4} +\frac{1}{2}[/tex]

[tex]\frac{1+2}{4} = \frac{3}{4}[/tex]

E) [tex]\frac{2}{8} +\frac{1}{4}[/tex]

[tex]\frac{2+2}{8} = \frac{4}{8} = \frac{1}{2}[/tex]

F) [tex]\frac{1}{4} -\frac{1}{6}[/tex]

[tex]\frac{3-2}{12} =\frac{1}{12}[/tex]

G) [tex]\frac{1}{3} +\frac{2}{3} +\frac{4}{3}[/tex]

[tex]\frac{7}{3}[/tex]

H) [tex]\frac{9}{4} -\frac{1}{4} -\frac{3}{4}[/tex]

[tex]\frac{5}{4}[/tex]

I) [tex]\frac{4}{5} + \frac{5}{2} +\frac{5}{6}[/tex]

[tex]\frac{24+75+25}{30} =\frac{124}{30} = \frac{62}{15}[/tex]

J) [tex]\frac{8}{15} +\frac{4}{15} -\frac{1}{5}[/tex]

[tex]\frac{8+4-3}{15} = \frac{9}{15} = \frac{3}{5}[/tex]
